• update coins every 1 second or when u refresh (refersh indicator) + refresh button from app bar
• add the sparkline to the list
• sort by table head item
• at 743. it gets stuck
• i should remove the bg colour of the icon
• 9-10, 99-100 they are not alineated
• when u get to the end of the table, dispay table end
• add the coin vs coin on exchange: https://min-api.cryptocompare.com/data/v2/pair/mapping/exchange/fsym?exchangeFsym=BTC&limit=1000&exchange=binance
• change error coin img/handle it differently
• add an i button after the 'end of list', show: To add a coin to favorites: Tap on a coin on the trades page, and then star it.

Coin screen

• solve the delay with the snakebar

Positions

• execute an order only if there are no errors (not allow negative balance)
• add create, delete, modify virtual portofolio
• add real money positions
• pup-up before buying?
• make more efficient when calculating the ballance: request all the data in only one http request

Settings page

• theme
• user: log out, delete account

Home page

• Add welcome/welcome back

Maybe usefull

• visualDensity: VisualDensity.adaptivePlatformDensity, (in ThemeData)
• elevation (AppBar)
• ChangeNotifierProvider
• await DesktopWindow.setMinWindowSize(const Size(600, 800));

Chosing API

For now: CryptoCompare: simple, free, most popular, lots of tutorial When i wanna be able to buy and sell: binance api

• i want to request every 2 seconds new values

1. CoinMarketCap: u get only 1000 free credits and i need at least 0 x 60 x 60 x 24 x 30 = 51,840,000 requests per month
2. CoinGecko API: most popular, only 1 year hystorical data
3. CryptoCompare api: very popular, already example with flutter

• I already build some functionalities with binance api and coingecko but the 10-30 request a min are too little for me
